We just moved into a 50 year old house and all the windows need major repair scraping, painting, and
glazing. They are 9 pane glass. We were planning on repairing them but are unable to find information on glazing. Do you have any information? Should we bother going to all the work, or would it be better (and cheaper) to opt for replacement windows?
Deciding to save the windows or replace them depends on a couple things. Your windows with 9 panes are probably a style which being old is not easily replaced and may well compliment your house's looks. On the other hand, they will not be as tight and being single pane, not as energy efficient. Sometimes aesthetics outweigh efficiency.As for reglazing, it is not too hard. You should pick out all the old hard glazing and then put in new. It is sold in tubes (like caulking) which makes installing it easier. Squeeze it in and then use a putty knife to wipe it flat into anice triangular bead.

Why does the glazing around my windows keep shrinking and coming loose? I remove the old glazing first and make sure it is clean before applying the new glazing compound, but it only lasts about a year before I have to do it again?
Make sure the glazing you are using is fresh and still pliable. Old glazing is prone to the problems you describe. Very dry wood in the window frames can contribute to this. Finally, try painting over the glaze after it has cured a while, this will let it dry more slowly and evenly.
Old window putty
The problem is how to soften putty on a metal window frame in order to remove the glass.
Use a heat gun or a torch like the one you use to solder pipe. Warm the glazing and scrape it out with a stiff putty knife. Go slow and wear safety glasses and gloves.
